Description

Technical Field

[0001] The present invention relates to the technical field of emergency clinical equipment, and particularly to a cardiopulmonary resuscitation rescue device for emergency clinical use. Background Art

[0002] Cardiopulmonary resuscitation first aid mainly includes four aspects: judging the patient's respiratory and cardiac arrest, performing external chest compressions, opening the airway, and artificial respiration. For adult patients, once the patient has no response and has no breathing or cannot breathe normally, external chest compressions should be immediately performed. Currently, traditional external chest compressions are basically performed manually by doctors. However, as the number of compressions increases, the doctor's arm will feel tired, and the force may become smaller. Once the force is insufficient, the standard of cardiac resuscitation will not be achieved.

[0003] For this reason, Chinese Patent with the publication number "CN112641620A" discloses "a cardiopulmonary resuscitation rescue device for emergency clinical use". Its main structure includes a support plate. A slideway opening penetrates through the plate surface of the support plate. A slider is slidably connected in the slideway opening. One end of the support plate is provided with a pushing mechanism for driving the slider to slide. The lower surface of the slider is fixedly installed with a housing. A through hole is provided at the bottom end of the housing. A guide cylinder is fixedly installed on the inner side wall of the through hole. A guide rod is slidably connected to the inner side wall of the guide cylinder. The bottom end of the guide rod is fixedly installed with a pressing head. A driving motor is fixedly installed on the inner side wall of the housing. The output end of the driving motor is fixedly sleeved with a main transmission wheel. This cardiopulmonary resuscitation rescue device for emergency clinical use adopts mechanical automatic pressing. Doctors only need to adjust the position of the pressing head and control the number of compressions to complete the compression first aid. Compared with the manual pressing method, it is closer to the standardization of cardiac resuscitation and improves the success rate of first aid.

[0004] However, the above-mentioned cardiopulmonary resuscitation rescue device for emergency clinical use uses the piston principle for cardiac compression. Since the length of the guide rod is a fixed value, the compression depth of the pressing head will be at a fixed position each time, and it is very difficult for the staff to judge the compression depth of the heart (the compression depth of each person's heart is not the same). Therefore, it is very easy to occur the phenomenon of insufficient or excessive compression depth, resulting in negative impacts. Summary of the Invention

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 and Figure 2 , an emergency clinical cardiopulmonary resuscitation rescue device, including a bottom fixed substrate 1, a top support substrate 2 located above the bottom fixed substrate 1, a component fixed port 3 provided in the top support substrate 2, and a pressing head 4 for pressing and contacting the heart. The bottom fixed substrate 1 is fixedly installed in the working area through bolts. The patient needs to lie below the pressing head 4, and the heart part needs to be directly below the pressing head 4.

[0023] To achieve the function of adjusting the pressing height, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , it is necessary to set up a support height adjustment mechanism 5, which is internally provided with a first external threaded rod 56 and a second external threaded rod 57 connected to the bottom fixed substrate 1 and the top support substrate 2, a longitudinal threaded sleeve 51 that is threadedly connected to the first external threaded rod 56 and the second external threaded rod 57 and can change the distance between the first external threaded rod 56 and the second external threaded rod 57 when rotating, and a polygonal limiting rod 511 inserted at the axis of the first external threaded rod 56 and the second external threaded rod 57 and capable of preventing the relative rotation between the first external threaded rod 56 and the second external threaded rod 57. According to the actual situation of the patient, rotate the polygonal rotation structure 512. At this time, the longitudinal threaded sleeve 51 will rotate in a specific direction. Since the cross-sectional structure shape of the polygonal limiting cavity 510 is the same as that of the cross-sectional structure shape of the polygonal limiting rod 511, both are polygonal structures, and the cross-sectional structure size of the polygonal limiting cavity 510 matches the cross-sectional structure size of the polygonal limiting rod 511, and the first thread structure 54 includes an internal thread structure provided inside the first internal thread cavity 52 and an external thread structure provided on the rod body of the first external threaded rod 56, the second thread structure 55 includes an internal thread structure provided inside the second internal thread cavity 53 and an external thread structure provided on the rod body of the second external threaded rod 57, and the spiral direction of the first thread structure 54 is opposite to the spiral direction of the second thread structure 55. At this time, the first external threaded rod 56 and the second external threaded rod 57 will move closer to or away from each other, thereby achieving the function of adjusting the pressing height.

[0024] Regarding the specific structure of the support height adjustment mechanism 5, please refer to Figure 3 and Figure 4, including a longitudinal threaded sleeve 51 with a polygonal rotating structure 512 facilitating screwing on its outer circumferential surface, a first outer threaded rod 56, and a second outer threaded rod 57. One end of the longitudinal threaded sleeve 51 is provided with a first internal threaded cavity 52 of a concave structure, and the other end of the longitudinal threaded sleeve 51 is provided with a second internal threaded cavity 53 of a concave structure. The rod body of the first outer threaded rod 56 is installed inside the first internal threaded cavity 52 through a first threaded structure 54, and the rod body of the second outer threaded rod 57 is installed inside the second internal threaded cavity 53 through a second threaded structure 55. The first outer threaded rod 56 and the second outer threaded rod 57 are provided with a polygonal limiting cavity 510 of a concave structure at their opposite ends. A polygonal limiting rod 511 inserted into the polygonal limiting cavity 510 is fixedly installed at the center of the longitudinal threaded sleeve 51. One end of the first outer threaded rod 56 is provided with a first connecting plate 58 integrally formed with it and fixedly connected to the upper surface of the bottom fixed substrate 1, and one end of the second outer threaded rod 57 is provided with a second connecting plate 59 integrally formed with it and fixedly connected to the lower surface of the top support substrate 2.

[0025] In order to achieve a flexible pressing effect on the patient's heart, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , a liquid expansion-driven mechanism 6 needs to be set up. Inside it, there is a longitudinal hollow body 61 fixedly installed in the component fixing port 3 and with a hollow interior, a piston body 67 placed inside the longitudinal hollow body 61 and driving the pressing head 4 to move downward after being subjected to liquid pressure, and an elastic airbag 611 that elastically expands outward after being subjected to liquid pressure. During operation, the liquid flow channel 65 is docked through a pipeline with the liquid return channel of a hydraulic device capable of controlling the liquid flow pressure and the liquid flow circuit. When the hydraulic device is started, the liquid enters the liquid reserve cavity 64 inside with a certain pressure. Under the action of the liquid, the piston body 67 will drive the pressing head 4 to move downward and press on the patient's heart. During the pressing process, the pressure of the liquid will generate an outward pressure on the inner side of the elastic airbag 611, causing the elastic airbag 611 to elastically expand. This phenomenon can make the pressing head 4 press the heart in a flexible direction, thus achieving a flexible pressing effect on the patient's heart. When a single downward pressing is completed, the hydraulic device is started to make the liquid flow back. Under the elastic action of the spiral spring 69, the liquid will flow back quickly. Similarly, repeated pressing actions are carried out.

[0026] Regarding the specific structure of the liquid expansion-driven mechanism 6, please refer to Figure 5 and Figure 6, including a longitudinal hollow body 61, an annular fixing groove 62 for fixedly mounting the fixing port 3 of the component is arranged on the outer circumferential surface of the longitudinal hollow body 61 near its bottom end, a longitudinal component moving cavity 63 is arranged inside the longitudinal hollow body 61, a liquid reserve cavity 64 is arranged at the top end of the longitudinal hollow body 61, liquid flow channels 65 communicating with the liquid reserve cavity 64 are arranged on both sides of the top end of the longitudinal hollow body 61, a liquid compensation hole 610 communicating the top area of the longitudinal component moving cavity 63 and the external space is arranged on the circumferential surface of the longitudinal hollow body 61, an elastic airbag 611 is sleeved on the circumferential side surface of the longitudinal hollow body 61 around the liquid compensation hole 610 through a fixing ring 612, a piston body 67 capable of axially moving along the longitudinal component moving cavity 63 is placed inside the longitudinal hollow body 61 in the longitudinal component moving cavity 63, a rod body through hole 66 communicating the external space and the bottom end of the longitudinal component moving cavity 63 is arranged at the bottom end of the longitudinal hollow body 61, a longitudinal telescopic rod 68 penetrating through the rod body through hole 66 is fixedly installed at the bottom end of the piston body 67, a pressing head 4 is fixedly installed at the bottom end of the longitudinal telescopic rod 68, and a compressed spiral spring 69 is sleeved on the outer periphery of the rod body of the longitudinal telescopic rod 68 inside the longitudinal component moving cavity 63.

[0027] During use, the bottom fixing substrate 1 is fixedly installed in the working area by bolts. The patient needs to lie below the pressing head 4, and the heart part needs to be directly below the pressing head 4. According to the actual situation of the patient, the polygonal rotating structure 512 is rotated. At this time, the first external threaded rod 56 and the second external threaded rod 57 will move closer to or away from each other, thereby realizing the function of adjusting the pressing height. The hydraulic device is started to make the liquid enter the liquid reserve cavity 64 with a certain pressure. Under the action of the liquid, the piston body 67 will drive the pressing head 4 to move downward and press the patient's heart. During the pressing process, the pressure of the liquid will generate an outward pressure on the inner side of the elastic airbag 611, causing the elastic airbag 611 to expand elastically. This phenomenon can make the pressing head 4 press the heart in a flexible direction, thereby realizing the flexible pressing effect on the patient's heart. When a single downward pressing is completed, the hydraulic device is started to make the liquid flow back. Under the elastic action of the spiral spring 69, the liquid will flow back quickly. Similarly, repeated pressing actions are performed.
